This one only lasted going on 3 years. Checked everything out pump-wise and it appears to be the motor. I found a replacement for it, which lists this model as 1hp. They also had the "same" motor in other sizes and also a 2 speed. I was thinking of going down to 3/4hp, for both effenciency and supposedly it would actually clean the pool better. I wanted to go to a 2 speed if I could, but I'm not sure if it's a direct swap out? Can't see a reason why it wouldn't be, but I'm no expert.
